This section or segment has a flat I have shown apreferred embodiment of my forward end I9 adapted to seat firmly and fitinvention in the accompanying drawing, in closely against the seatingface I0 of the portion Which- 9 of the main body 5 of the cooler proper.The 50 Figure 1 is a longitudinal section through the faces 8 of theopening in thel cooler body 5 are improved cinder notch cooler assembly,with the provided with semi-circular notches 2t which are separablesection removed; adapted to coact with similar notches 2| formed Figure2 is a view similar to Figure 1 but showin the meeting faces of thereplaceable segment ing the separable section of the main cooler; I3.These notches When in registration are 55 adapted to receive dowel pinswhich will maintain the parts in proper intertting relationship. Thesection I8 as shown in Figure 4, is provided with the tapped openings22, one of which may be used to introduce the cooling iluid and theother to withdraw it.

It will be understood that the assembly will be inserted so as to extendthrough the furnace Wall with the segment I8 at the lower position asshown in gures of the drawing. Thus when the cooler is used to withdrawcinder from the furnace it will pass over the movable section I8 andwill normally never be in suflicient quantity of flow to engage the bodyof the cooler. It will be understood that normally the cinder will notdestroy any portions of the cooler. If, however, in the furnaceoperation the molten metal gets high enough so that some of it runs outwith the cinder, this molten metal may cut through and ruin one or moreof the portions of the assembly. If it cuts through the money 1, thatmay be withdrawn and replaced with a new casting without aiecting theother portions of the assembly. If it should cut through theintermediate section 6, this may be remove-d, carrying with it themonkey which, if not damaged, may be placed in a new intermediatesection and the sub-assembly restored to its position in the main bodyof the unit. As has been previously stated, these replacements requiremuch less loss of time and expense than replacement of the entireassembly.

Similarly, should the main cooler be cut through by the molten metal,this cutting will only affect the segment I8. This segment may bereadily removed without disturbing any of the other sections of theassembly. It is merely necessary to knock out the dowels extending intothe notches and 2|, whereupon the section may be rea-dily withdrawn anda new one inserted without delay or loss of furnace time.

The construction is so designed that an integral finished surfaceextending throughout the whole circumference is formed on the maincooler 5 to receive the intermediate cooler 6. This is important inmaintaining an airtight joint at this point. It also facilitates removalof the injured section when necessary.

While I have described my invention as a cinder notch cooler, it will beapparent that it may also be used as a tuyre cooler. Tuyre coolers aresometimes burned through by iron burning through blow pipes. With myimproved cooler used in tuyres it would save the replacement of theentire cooler in such cases and be effective in the same manner as whenused as a cinder notch cooler.

Although I have described my invention with the use of copper as thematerial, it will be understood that cast iron is sometimes used.

The segment which is inserted may also be made of cast iron, or in somecases, of refractory material, or it may be made of cast iron with acoating of refractory material on a surface where it is not desired towater cool it.

While I have shown one form of my invention, this is to be understood tobe illustrative only, as the invention is capable of change andmodification to meet varying conditions and requirements and Icontemplate such modifications as come within the spirit and scope ofthe appended claims.

I claim:

1. A furnace wall opening hollow cooler comprising a cooler bodygenerally frusta-conical in shape having its smaller end in the form ofan unbroken circle and having a hollow removable section of substantialarcuate and axial extent, said section forming a portion of the largerend of the body and meeting a radial inner face of the circular sectionadjacent the small end of the body.

2. A furnace wall opening cooler comprising a cooler body generallyfrusto-conical in shape having its smaller end in the form of anunbroken circle, the inner face of said circle forming a continuousseat, a second cooler member having an outer face engaging said seat,the cooler body having a removable segment extending from the large endof the body to a point adjacent the seat.

Y 3. A furnace wall opening cooler comprising a cooler body generallyfrusto-conical in shape having its smaller end in the form of anunbroken circle, the inner face of said circle forming a continuousseat, a second cooler member having an outer face engaging said seat, aradially extending face on a portion of the said circular portionadjacent said seat, and a removable segment of the cooler body having anend fitting against said radially extending face.
